Note
cx_Oracle has a major new release under a new name and homepage python-oracledb.
New projects should install python-oracledb instead of the obsolete cx_Oracle driver.
Python-oracledb uses the same Python Database API as cx_Oracle, supports the feature requirements of frameworks that rely on this API, and has many new features.
To upgrade to python-oracledb, see Upgrading from cx_Oracle 8.3 to python-oracledb.
